There’s so much to do this weekend to celebrate Independence Day in the Boston area, but the weekend kicks off with temperatures reaching the 90s on Friday.

At Christopher Columbus Park, there will be a concert and fireworks display Friday night as part of Boston Harborfest. The 4th of July festival celebrating Boston’s port and history kicks off Friday with events at Downtown Crossing, including the U-turn sail of the USS Constitution.

Meanwhile, Friday night and Saturday, Boston JerkFest brings incredible Caribbean cuisine to the Harvard Athletic Complex. And of course, the crown jewel of Boston’s 4th of July celebrations is the Boston Pops Fireworks Spectacular on Monday at the Esplanade.

Thursday was expected to be one of the busiest travel days on the road for the 4th of July weekend. Triple A Northeast predicts Boston-area drivers could experience up to 3 times the usual traffic on select roads Thursday and Friday.

But the weather is going to be warm with temperatures in the 90s on Friday, and the weekend in the 80s and humid. The NBC10 Boston weather team issued an initial alert Friday for scorching temperatures.

For those attending any of these outdoor events, experts say they want to watch for signs of heatstroke. If you are not sweating, have dry, hot and red skin, sharp pupils, dizziness or headache, vomiting or fainting, you should see a doctor.
